The Eaton switched combiner provides a single point to combine incoming photovoltaic strings and disconnect dc power close to PV modules, uniting Eaton’s 600 Vdc solar disconnect and source-combiner box in one enclosure. Fusible versions of this combiner allow isolation of the fuse when the switch is in the “off” position. The fuse holders are hard-bussed to the main disconnect, and the enclosure allows for mounting in vertical or horizontal orientations. Options include surge protection, current monitoring, and wireless communication. This monitor measures dc current per channel, as well as total and average dc current.
